Managing git credentials in MS Windows

Tue, 31 Mar 2026 21:16:36 +0200

In this entry I will document (for myself) how to setup a reasonably secure git credential management for WSL in Windows. I am no Windows fanboy but luckily WSL exists, and we should be careful with our access tokens even in Linux!

Mom, can we have anycast DNS?

Wed, 25 Mar 2026 21:51:51 +0100

After discovering diskless mode in Alpine Linux, I wanted to use it everywhere! But where to start…maybe it’s time to setup a BGP announced anycast DNS cluster with all the moving parts? All of this to avoid just using the reasonable tool¹ for the job!

Diskless Alpine Linux on a Raspberry Pi

Sat, 28 Feb 2026 11:32:33 +0100

Most container aware people are probably familiar with Alpine Linux, as it is commonly used as a container base – but few are familiar with using it as a full Linux distribution. Even fewer are aware that you can easily run Alpine Linux in diskless mode, which I think is great for SBCs like a Raspberry Pi.

Configure Incus containers using Ansible

Fri, 13 Feb 2026 13:01:07 +0100

This post will outline how I setup an Ansible playbook to manage a Incus container on a remote host. This was fairly straight forward¹ but I couldn’t find a suitable write-up elsewhere so here we go!

Implementing search on this site

Tue, 27 Jan 2026 09:02:56 +0100

I decided to add a search function to this blog, but this time I had to accept some browser side JavaScript for it to function. This entry will describe how I implemented this (using pagefind) on this site.

Light/dark theme for MermaidJS

Fri, 09 Jan 2026 23:56:46 +0100

Making my graphs respect the user system light- and darkmode settings was surprisingly straight-forward, and we are still not using any (browser side) JavaScript to accomplish this!

Adding icons to Mermaid charts

Sat, 22 Nov 2025 18:00:54 +0100

While we are ricing…enhancing this blog with MermaidJS charts, we might as well add icons to said charts as well! This was also surprisingly easy to do, so here we go…

Upgrading to a new Postgresql major version on NixOS

Thu, 20 Nov 2025 18:50:29 +0100

I’ve seen a few different guides on how to upgrade to a new major PostgreSQL version but couldn’t make it work as I’m also using extensions for some of my databases. Luckily this was relatively easy due to NixOS declarative nature!

Garage object storage, Caddy and dynamically provisioned TLS certificates

Wed, 12 Nov 2025 08:37:00 +0100

I recently started serving this website internally (as a “staging environment”) and discovered that Garage + Caddy can automagically serve sites & issue certificates per S3 bucket, as subdomains under the Garage domain name (*.garage.example.com). This entry will describe how I setup Garage, Caddy and dnsmasq to work together in my homelab setup.

Woodpecker CI, Hugo & MermaidJS

Tue, 11 Nov 2025 21:16:17 +0100

Fiddling around with Woodpecker CI was a lot of fun, so I finally implemented javascript-less MermaidJS graphs! It’s not perfect by any means but I think it is Good Enough(tm) and it involves some terrible regexps so here we go!
